I've bought Intel 520 120gb. I have ProBok 6465b and it stuck at first screen with HP logo when it is in notebook, in the place of primary HDD. When first boot to DVD with win 7, i can't install it due to information about lack of disk's controller in BIOS. In IDE mode everythin is ok. I can even install system but when try to chenge registry and re-boot, and change to AHCI on next re-boot it also stuck at first screen with HP logo.
Do I have to wait for new BIOS? Or can it be resolved in other way?
The HP Pro laptops are a nightmare, most have somthing called "HP Driveguard" which is probably what is causing the issue you are having. I doubt there is a way around it and there is a fair chance when you put the original hdd back in, it will not boot due to this 'feature'. If this is the case then the only way to get the machine working again is to send back to HP.
